Not exactly related, but I agree with the questionable quality of new production starter bendix assemblies….
I recently went to the trouble of replacing the starter bendix assy on a ‘49 Stude Champion, and ended up having to do the job twice! ……Although the starter would spin properly, the new bendix would not ‘throw out’ into the flywheel teeth… The starter would just spin…. The second bendix replacement seems to be working OK.
